Mastering Service Mesh

By: Anjali Khatri, Vikram Khatri

Overview of this book

Although microservices-based applications support DevOps and continuous delivery, they can also add to the complexity of testing and observability. The implementation of a service mesh architecture, however, allows you to secure, manage, and scale your microservices more efficiently. With the help of practical examples, this book demonstrates how to install, configure, and deploy an efficient service mesh for microservices in a Kubernetes environment. You'll get started with a hands-on introduction to the concepts of cloud-native application management and service mesh architecture, before learning how to build your own Kubernetes environment. While exploring later chapters, you'll get to grips with the three major service mesh providers: Istio, Linkerd, and Consul. You'll be able to identify their specific functionalities, from traffic management, security, and certificate authority through to sidecar injections and observability. By the end of this book, you will have developed the skills you need to effectively manage modern microservices-based applications.

Summary

In this chapter, we explored Consul Connect's traffic management features that are configured at the application layer. L7 configuration is achieved through centrally managed Consul primitives that can be replicated to other data centers, thereby providing service resiliency and redundancy through mesh gateways.

We explained service-resolver by defining subsets of services that can be used to split traffic through service-splitter for canary deployments and traffic shifting. We also explained using path-based routing to shift traffic to different services.

This brings us to the end of our studies and our hands-on exercises for the three popular service meshes in the industry today. The service mesh, which started in 2015, is a fairly new technology and continues to evolve. It remains to be seen whether it continues in its present form. We anticipate consolidation...
